Application filed March 17, 1921. Serial No. 452,901.

To all. to 710m it may concern:

Be it known that I, WVILLIAM. Ln ROY citizen of the United States, and a resident of Chickasha, in the county of Grady and State of Oklahoma, have invented certain new and useful Improvements in .Wrenches, of which the following is a specification.

This invention relates to a wrench, and more particularly to a combined pipe and nut wrench. The object of the invention is' Figure 1 is a longitudinal vertical sec tional view of the wrench, the forward or stationary jaw being shown ,in side elevation, 7

Figure 2 is an elevation showing the inner gripping face of the jaws,

igure 3 is a vertical cross section taken substantially on the lines 33 of Figure 1,

and also showing in elevation the rear end of the -movable jaw,

Figure 4: is a side elevation of the interiorly threaded sleeve for advancing or retracting the movable jaw and handle, and

Figure 5 is a perspective view of the lever bar. v

Referring to the drawings more particu-' larly, 10 indicates the forward or stationary jaw, and 11 the rearward ormovable jaw. One end portion of the opposing faces of the jaws is formed with teeth or serrations as indicated at 12, which are adapted to engage and grip the sides of a nut. The other opposing end portions of the jaws are likewise provided withteeth or serrations, as at 13, the last named teeth being in curved formation in order that they may be adapted to grip a, pipe.

From the inner face of the jaw 10 there extends a pair of guide pins 18 and from the same face of the jaw 10 intermediate of the pair of guide pins there extends a stem 14, said stemnand guide pins being disposed in parallel relation and the stem being greater in length and diameter, as sh0wn.

The jaw 11 is mounted to slide upon the guidejpins 13 and the stem 14. Suitable openings are provided in the jaw 11 through whichthe; guides 13 and stem 14- may pass. A-hollow handle 15 is provided, the stem 14: passing through the interior thereof.

The one end of the handle 15 is enlargedas at 16. The one end of this enlarged por-' tion of the handle is provided with a pair of openings 17 through which the guide pins '13 may pass; also at the end of each opening 17 a sleeve extension 18 is formed and extended into enlargement of the openings in the jaw llthrough which the guide pins 13 pass. The openings in the jaw 11 and enlarged portion '16 of the handle through which the guide pins 13 sutlicient so that no undue friction will be had against the sliding of the handle and jaw upon said pins. Likewise the jaw and handle are free to slide upon the stem 14.

On the free end of the stem 14 threads 20 are formed and adapted to receive the interiorly threaded sleeve 21. On therear portion of the sleeve 21, there is formed a collar 22 which limits the forward movement of the sleeve with respect to the handle 15; also the sleeve is held against 'movement rearwardly by the cooperation of the annular groove 23 formed in said sleeveand' the pin 24. The ends of the pin 24 extend through openings formed in the handle 15, not shown, and by a tight fitting-in said openings or other suitable means the pin is held against removal. The sleeve 21 is free for turning movement, but-held against longitudinal movement in either direction with respect to the handle 15.

In the collar 22 there is formed an opening 25 adapted to receive the lever bar'26. The opening 25 is preferably tangential with respect to the collar 22. The lever bar 26 is provided with an enlarged end as at 27 and its other end is provided with an opening 28 to accommodate a cotter pin or the like by which the same may be held agai opening 25.

In the operation of the present device, by

nst removal when positioned in "the pass are 7 inserting the lever bar 26 in the opening 25,

the sleeve 21 may be turned forward or backward which in turn will move with it the handlemember 15 and which in turn cartioned that great "gripping stress may be the jaw 11 maybe retracted or advanced in a positive manner. Also it may be menapplied between the two jaws. 7 If desired, the lever bar 26 need only be used when tightening iipthe jaws l0 and 11,101" aftef j the sameihave been' brought in contact with "the nut or pipe" upon which thewrench is intendedwto he used. At .other times, the

bar may 'be removed from the opening 25 a i 1 or retracting the stem 7 and jaws carried thereby, and-means for holding the sleeve 7 against longitudinal movement butfree for 30 a A wrench comprising-in combination, a

stem having a jaw formed upon-the one end thereof, a tubular handle 'telesceping j said stem seeend jaw c'ar'ried the 05 Ward endjofsaid handle, a sleeve in the.

rear end of said handle, compe'rating threads between said slee'veand stem permitting the stem to moveentirely' through the s1eeve,'a

collal formed on the rear end of; said sleeve against which the tubular handle isadapted to abut; said-collar having an openlng extending tangentially therethrough, a lever 25 bar extending through said opening whereby said sleeve may he turned for advancing rotative movement 7 V f x a e v.
